Corner connection block for assembly container

ABSTRACT

The present invention is chiefly applied to a corner connection block for connecting frames at each corner of an assembly container, such as an assembly cabinet, an assembly drawer, or an assembly box, etc with a fixed thickness base, wherein two rods, paralleling to each other, formed beneath, to be inserted in holes formed on each end of a frame, thereby firmly connecting two adjacent frames.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a corner connection block, in a form ofan unity, for connecting frames of an assembly container, such as anassembly cabinet, an assembly drawer, an assembly box, or an assemblyframe, etc and more particularly to utilize corner connection blocks tomake fast and firmly connection of frames at each corner of assemblycontainers thereof.

(b) Description of the Prior Art

Before shipping, to save packaging space, an assembly container, such asan assembly cabinet, an assembly drawer, an assembly box, or an assemblyframe, etc is usually in a disassembled form of frames and plates tofacilitate packing into a (carton) box. By assembling frames and platesthereof according to drawings provided, the assembly container therebyformed.

A conventional assembly container is usually formed with holes on eachframe or plate, to be connected by screws to fasten each correspondingframe or plate. Besides being complicated in screwing and assemblingprocess, the screwing to assemble method may cause holes thereof damagedor enlarged excessively to the extent that a re-use is impossible.

SUMMARY OF THE INVENTION

The present invention is mainly applied to a corner connection block forconnecting frames at each corner of an assembly container, such as anassembly cabinet, an assembly drawer, or an assembly box, etc, with twoframes formed at each corner and a hole formed on each end of a frame,to be inserted by rods formed beneath a base of the corner connectionblock, wherein the base is with a fixed thickness and each rod formedparalleling to the other, thereby enabling a fast and firm connection offrames for a layer of the assembly container.

In addition, rods thereof can also be formed on the base, thereby anupper and a lower layer of an assembly container can be formed.Moreover, a hinge structure can be formed on a top of the base thereof,to be hinged with a shaft rod formed on an end of a shaft of a lid or adoor.

To enable a further understanding of the said objectives and thetechnological methods of the invention herein, the brief description ofthe drawings below is followed by the detailed description of thepreferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2. An application, an assembly cabinet 10 (oran assembly drawer, or assembly box, or an assembly frame, etc), to besurrounded by weaving material of cloth or rattan, is formed by circulartube frames 11 on each corner, wherein a hole 12 formed on each end of aframe, to be inserted by a corner connection block 20 to form aconnection with other frames.

Referring to FIGS. 2 and 3. The corner connection block 20 is formed bya base 21 having a fixed thickness, wherein two cylinder rods 22,paralleling to each other, formed beneath the base 21, to be insertedinto holes 12 thereof to connect frames, thereby forming a layer of anassembly container. The corner connection block 20 can be formed with aflat surface to enhance appearance. Additionally, rods 22 thereof canalso be formed on the base 21, each in align with rods formed beneaththe base 21, thereby forming an upper and a lower layer of an assemblycontainer.

Referring to FIG. 4. A hinge connector structure 25 formed on a top ofthe base 21 of the corner connection block 20, with a hole 26 formedthereof, to be inserted by a shaft rod 13 formed on a shaft 11 (or otherequivalent structures) of a lid or a door, thereby enabling a lid or adoor hinged at the corner connection block 20 to rotate round the shaft11.

Referring to FIGS. 5 and 6. Tightening grooves 23 can be formed on anouter perimeter of the cylinder rod 22 along an axial or a radialdirection to enhance fixing effect. Referring to FIG. 2. A reinforcingstructure 24 can be formed on the connection of the rod 22 and the base21 to enhance a structure strength of the rod 22.

It is of course to be understood that the embodiment described herein ismerely illustrative of the principles of the invention and that a widevariety of modifications thereto may be effected by persons skilled inthe art without departing from the spirit and scope of the invention asset forth in the following claims.

1. A corner connection block for connecting frames at each corner,comprising two frames formed at each corner and a hole formed on eachend of a frame, to be inserted by rods formed beneath a base of thecorner connection block, wherein the base is with a fixed thickness andeach rod formed paralleling to the other, thereby enabling a firmconnection of two adjacent frames.
 2. The corner connection block asrecited in claim 1, wherein rods can be of a cylinder type.
 3. Thecorner connection block as recited in claim 1, wherein tighteninggrooves formed on the rod.
 4. The corner connection block as recited inclaim 3, wherein tightening grooves formed along an axial direction. 5.The corner connection block as recited in claim 3, wherein tighteninggrooves formed along a radial direction.
 6. The corner connection blockas recited in claim 1, wherein rods also formed on the base of thecorner connection block.
 7. The corner connection block as recited inclaim 6, wherein each rod formed on the base in align with that formedbeneath the base.
 8. The corner connection block as recited in claim 1,wherein a hinge connector structure formed on a top of the base of thecorner connection block, with a hole formed thereof.
 9. The cornerconnection block as recited in claim 1, wherein a reinforcing structureformed on the connection of the rod and the base of the cornerconnection block.
